2. Securities have been sold abroad and the seller is drawing on the buyer for the purchase price.
3. Foreign money is being loaned in this market, the operation necessitating the drawing of drafts on the lender.
4. Finance-bills are being drawn, i. e., a banker abroad is allowing a banker here to draw on him in pounds sterling at 60 or 90 days' sight in order that the drawer of the drafts may sell them (for dollars) and use the proceeds until the drafts come due and have to be paid.
1. Looking at these sources of supply in the order in which they are given, it is apparent, first, that a vast amount of foreign exchange originates from the direct export of merchandise from this country.
Not all merchandise is drawn against; in some cases the buyer abroad chooses rather to secure a dollar draft on some American bank and to send that in payment. But in the vast majority of cases the regular course is followed and the seller here draws on the buyer there.
2. The second source of supply is in the sale abroad of stocks and bonds.
Origin of bills from this source is apt to exert an important influence on rates, in that it is often sudden and often concentrated on a comparatively short period of time. The announcement of a single big bond issue, often, where it is an assured fact that a large part of it will be placed abroad, is enough to seriously depress the exchange market. Bankers know that when the shipping abroad of the bonds begins, large amounts of bills drawn against them will be offered and that rates will in all probability be driven down.
3. The third great source of supply is in the draft which bankers in one country draw upon bankers in another in the operation of making international loans. The mechanism of such transactions will be treated in greater detail later on, but without any knowledge of the subject whatever, it is plain that the transfer of banking capital, say from England to the United States, can best be effected by having the American house draw upon the English bank which wants to lend the money. The arranging of these loans means the continuous creation of very large amounts of foreign exchange.
4. Drawing of so-called "finance-bills," is the fourth source whence foreign exchange originates. Whenever money rates become decidedly higher in one of the great markets than in the others, bankers at that point who have the requisite facilities and credit, arrange with bankers in other markets to allow them (the bankers at the point where money is high) to draw 60 or 90 days' sight bills. These bills can then be disposed of in the exchange market, dollars being realized on them, which can then be loaned out during the whole life of the bills.
These are the principal sources from which foreign exchange originates—shipments of merchandise, sales abroad of securities, transfer of foreign banking capital to this side, sale of finance-bills. Other causes of less importance—interest and profits on American capital invested in Europe, for instance—are responsible for the existence of some quantity of exchange, but the great bulk of it originates from one of the four sources above set forth.
